ROAD- SCBAIER.

Specification of Letters Patent. Patented Mar. 23, 1915.

Application filed May 9. 1914. Serial No. 837,511.

T all whom it may concern: Be it known that I, W'Aun S. BUNKER, a citizen of the United States, residing at Biloxi, in the county of Harrison and State of Mississippi, have invented QBW and useful Improvements in Road-bcrapers, of which the following is a specification. This invention provides an implement intended most especially for leveling and resurfacii'ig highways and country roads, said implement being of such fonmation as to move the earth from the sides of the road toward the center thereby raising the middle of the roadand insuring proper drainage and atthe same time filling the rats and other depressions whereby a level and comparatively smooth surface is obtained.

The invention relates more particularly to the means or draft connections whereby the implement is adapted to-be hitched to a motor vehicle and drawn thereby over the road tube leveled and resurfaced, the'draft attachments being such as to prevent lateral displacement of the-implement while at the same time admitting o f a limited play which is essential to good work.

The invention consists of the novel features,"'details of construction and combination of parts, which hereinafter will be more particularly set forth, illustrated and claimed;

In the drawings hereto attached Figure 1 is a top plan view of a road scraper embodying the invention showing the. same hitched to a motor vehicle the rear portion of the latter being illustrated. Fig. 2 is a side vicwi Fig. 3 is a detail \'l('\\ in perspective of the road scraper. p

(.orresponding and like parts are referred to in the following description. and indi catcd in all the views of the. drawing, bythc same reference characters.

The implement comprises side bars 1 and cross bars 2. and El the latter connectin; the side bars 1 near their ends. The side bars 1 are oppositely inclined with their front ends spread and their rear ends brought together. The spread of the bars 1 at their front ends is usually about nine feet but will depend largely upon the width of the roadway to be leveled and resurfaced.

The rear ends of the side bars 1 are. separated about eighteen inches so as to bring the surplus earth and stones to thevccnter of the road. Scraping blades 4 are secured to the-inner lower edges of the side. bars II For supporting the implement a truck is.

provided, the same comprising an axle 5 and wheels 6. A pole 7 projects forwardly from the axle 5 and short chains 8 and 9 connect the pole 7 wits the respective cross bars2and 3. A cross bar 10 is coupled at a middle pointto the front end of the pole 7 and is adapted to be secured atits er. s t7) the side springs 11 of a motor ehicle by means of clips 12 or other fastenm'gs/ Chains 13 are attached t; .he front ends of the side bars 1 and are forwardly converged and are connected at their front ends to a ring 14. Other chains 15 have their rear ends attached to the ring 14 and are for wardly diverged and are adapted to be se- 11 preferably in advance of the axle 16. it will thus be understood that thedraft is divided-between the pole 7 and side bars Land is distributed upon the springs 11, both in front of and in the rear of the axle 16. When the implement is drawn over the road the earth, stones and other material at the sides of the road is moved inward cured at their front ends tothe side springs by means of the side bars 1 thereby filling the-ruts and-depressions, the surplus material collecting in the middle of.the roadwhere it may be conveniently removed. By

this means the center of the road is elevated thereby insuring good drainage. WVhile the movement the arrangement of the. draft connections is such as to prevent any excessive play. hence satisfactory'results are obtained by a single travel of the implement over the road to be leveled and resurfaced.

From the foregoing description, taken in connection with the accompanying drawings. the-advantages of the construction and of the method 'of operation will be readily apparent to those skilled inthe art to which the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the invention as claimed.

Having thus described the invention, 'what is claimed as new is:

1. In an implement of the character described, the comb nation of a truk, a pole extended forwardly from thetruck. across bar connected at a middle point to the front end of ,the3 pole and provided at its ends with fastenings to make connection with the side springs of a motor vehicle, a road scraper, flexible front and rear connections between the sides of the pole and the front and rear ends of the road scraper, forwardly converged draft connections attached to the front end of the road scraper, other draft connections attached to the front ends of the converged connections and forwardly diverged and fastening means at the forward ends of the last mentioned draft connections for attachment to the side springs of a motor vehicle. a

2. In an implement of the character described, the combination of a truck, a pole extended forwardly from the truck, a cross bar connected at a middle point to the front end of the pole and provided at its ends with fastenings to make connection with the side springs of alnot-or vehicle, at a point in rear of the rear axle thereof, flexible front and rear connections between the sides of the pole and the front and rear ends of'the road scraper, forwardly converged draft connections for attachment to the side springs of a motor vehicle at a point in advance of therear axle thereof.

In testimony whereof I affix my signature in presence of two witnesses.
